The Tyco CPU801 is the Central Processor Unit designed for use within the Tyco MZX series fire alarm and detection systems. As the core intelligence of the fire alarm panel, this unit manages system logic, loop communication, event processing, and alarm output functions. Onboard vessels, the CPU is a critical component within the fire detection infrastructure, ensuring that alarm signals are processed, logged, and actioned in accordance with operational requirements. A functioning CPU is essential to the continuous and reliable operation of the fire alarm system, making it a key safety-critical spare for any vessel operating Tyco MZX fire detection equipment.
Key Features
✓ Functions as the central processing unit for the Tyco MZX fire alarm panel, managing system logic, event handling, and alarm processing.
✓ Supplied with software version V22.00.00 pre-installed; PCB reference 125.165.515, Issue 02 — technical compatibility subject to confirmation for specific panel configurations.
✓ Designed as a spare module for MZX series fire alarm systems; compatibility with specific panel variants and firmware versions should be verified prior to installation.
✓ Intended for installation within the fire alarm control panel enclosure in a protected, dry onboard environment; relevant to SOLAS fire detection system requirements.
✓ Replacement of this module should be carried out by qualified personnel familiar with Tyco MZX system architecture; software version alignment with the existing system is recommended before commissioning.
Marine Applications
✓ Main fire alarm control panels aboard merchant vessels, tankers, bulk carriers, and container ships operating Tyco MZX detection systems.
✓ Passenger vessels and cruise ships where continuous, reliable fire alarm processing is mandated under SOLAS chapter II-2 requirements.
✓ Offshore platforms and FPSOs utilising Tyco MZX fire and gas detection infrastructure requiring CPU-level spare components.
✓ Naval auxiliaries, ro-ro ferries, and cargo vessels where fire alarm system uptime is critical to vessel safety and port state compliance.
✓ Vessel refit and drydock projects requiring like-for-like CPU replacement to restore or upgrade existing Tyco MZX fire alarm panels.
Why Marine Engineers Choose
